Abstract

The invention relates to a key, having a key head and a key shank (10), wherein the key shank (10) has an in particular cold-worked torsion section (20) at least in some sections along the longitudinal axis (L), wherein the key shank (10) has a base cross-section (26) in a region of transition to the torsion section (20), wherein the cross-section (30) of the key shank (10) in the torsion section (20) protrudes beyond the base cross-section (26) at least in some sections in the direction toward the key tip (70). The inventive concept is that the key shank includes a profile element that is configured as a longitudinal groove, wherein the profile element also includes a torsion in the torsion section, wherein the key tip is formed as a portion of the torsion section and is continuously twisted about the longitudinal axis (L) of the key shank, and, wherein the key tip is not congruent to the first section of the key shank.

Claims (14)

PATENT CLAIMS
1. A key, comprising: a key head; and a key shank, wherein the key shank includes first section that is adjacent to the key head and a torsion section that adjoins the first section and is formed, in particular cold formed, along a longitudinal axis (L) at least in sections, wherein the key shank includes a base cross-section in a transition portion to the torsion section, wherein a cross-section of the key shank protrudes at least in sections beyond the base cross-section in the torsion section in a direction towards the key tip, wherein the key shank includes at least one profile element that is configured as a longitudinal groove, wherein the profile element also includes a torsion in the torsion section, wherein the key tip is formed as a portion of the torsion section and is continuously twisted about the longitudinal axis (L) of the key shank, and, wherein the key tip is not congruent to the first section of the key shank.
2. The key with the key head and the key shank, according to claim 1, wherein the key shank is arranged at least in sections, wherein a length (A) and a torsion angle ( ?) of the key shank is variable in the torsion section in the direction towards the key tip.
3. The key according to claim 1 or 2, in particular according to claim 2, wherein the torsion section is configured as a control curve or includes a control curve.
4. The key according to one of the preceding claims, wherein at least one flank and/or an edge of the key shank protrudes beyond the base cross-section.
5. The key according to one of preceding claims, wherein the key shaft includes at least one coding element that is configured in particular as a recess in an edge.
6. The key according to one of the preceding claims, wherein at least two profile elements that extend parallel to one another in a first section that starts at the key head are twisted about the longitudinal axis (L) of the key shank in an adjoining torsion section and are advantageously arranged double helix-shaped.
7. The key according to one of the preceding claims, wherein at least the key shank is made from at least one of: an elastic material, spring steel, polyurethane, and PUR D 44.
8. The key according to one of the preceding claims, wherein the key shank is rotatably supported in the key head.
9. A lock, in particular configured to receive the key according of the claims 1 through 8, wherein the lock includes a locking cylinder with a cylinder core, wherein at least one decoding element is configured in the cylinder core, wherein the decoding element includes an arcuate, in particular helical, contour at least in sections, or the decoding element is arranged on an arcuate, in particular helical, path.
10. The lock, according to claim 9, wherein the arcuate, in particular helical path, extends along a base profile of the cylinder core.
11. The lock according to claim 9 or 10, wherein plural decoding elements configured as scanning elements are arranged on a helical path.
12. The lock according to claim 9 or 11, wherein at least one decoding element is configured as an arcuate, in particular helical, protrusion, or as an arcuate, in particular helical, recess.
13. The lock according to one of the claims 9 through 12, wherein a coupling element which scans the tip, in particular the tip associated with the torsion section.
14. The locking system, comprising: the key according to one of the claims 1 through 8 and the lock according to one of the claims 9 through 13.
